GEORGE J. KREBS, OF FREMONT, OHIO.

POST-OFFICE DELIVERY-WINDOW.

SPECIFICATION forming' part of Letters Patent No. 226,759, dated April20, 1880.

Application filed March 4, 1880. (No model.)

To all whom it may concern Be it known that I, GEORGE J. KREBs, ofFremont, in the county of Sandusky, and in the State of Ohio, haveinvented certain new and useful Improvements in Delivery-Windows forPost-Offices and I do hereby declare that the following is a full,clear, and exact description thereof', reference being had to theaccompanying drawings, making a part of this specication, in which-Figure l is a perspective view of my window from the outside. Fig. 2 isa like view of the same from the inner side. Fig. 3 is a perspectiveview of said window from the inner side, the pivoted sash being` turnedso as to permit 0f the delivery of large packages; and Fig. 4 is ahorizontalsection of the sash through the delivery-opening.

Letters of like name and kind refer to like parts in each of thefigures.

Much difficulty has heretofore been experienced in post-offices inclosing the opening used for the delivery of letters, packages, dto., soas to afford proper security to the contents of the office and protectthe delivery-clerk from exposure to injurious drafts, and for thispurpose many expedients have been employed; but all of such expedientshave proved unsuccessful, and a hinged or sliding sash is generally usedfor closing the delivery-opening.

To remedy the before-named difculties is the design of my invention,which consists, principally, in a delivery-window closed by avertically-pivoted sash which has a horizontal table, and immediatelyabove the same is provided with a narrow horizontal opening,substantially as and for the purpose hereinafter shown.

It consists, further, in the especial construction of the pivoted sashand its connections, substantially as and for the purpose hereinafterset forth.

In the annexed drawings, sent the sides, B the bottom, and C the top, ofa delivery-window, which has, preferably, a depth from front to rearequal to its width. Within the window is placed a sash, D, which hassuch dimensions and shape as to close the space when placed in theposition shown in Figs. l and 2, and is pivoted therein by means of twobearing-studs, E- and F, one of which A and A repreprojects verticallyfrom each end at its center,

and lits into a correspondingly-shaped socket that is provided withinthe contiguous top or bottom piece, C or B, respectively. The lowerstud, E, is rigidly attached to said sash, While the upper stud, F, iscapable of being drawn downward, so as to disengage it from said toppart, C, and enable said sash to be removed. Said stud F is held at theupper limit of its motion by means of a spring. llhe sash thus pivotedmay be placed across and caused to close the window-opening, as shown byFigs. l. and 2, or it may be turned into line with said opening', asseen in Fig. 3, in which latter position there is a clear space uponeach side of said sash equal to one-half the dimensions of thewindow-opening less one-half the thickness of said sash.

At or near the vertical center of the sash D is provided a circulartable, Gr, which has a diameter nearly or quite equal to the width ofsaid sash, and extends horizontally to equal distances upon each side ofthe same. Immediately above said table is an opening, d, that extendshorizontally between t-he side rails of said sash, and has verticallysufficient dimension to permit of the passage of an ordinary newspaperor unusually thick letter, which opening is inclosed, when desired, bymeans of a metal plate, H, (shown suspended in Fig. 2,) that corresponds'therewith in vertical dimensions, but has slightly greater length, sothat when in position, as seen in Fig. 3, one end of said plate fitsinto a recessd, in one of the side rails of said sash, While its otherend its into a rabbet, d2, within the inner face of the opposite rail,and is locked in place by means of a button, I, that is pivoted uponsaid rail. When not in use said plate is suspended from a stud or pin,d3, which projects from the inner face of one of said side rails.

A spring-catch, K, placed within one edge of the sash D, and arranged toengage with lthe socket a, that is provided within one of thewindow-sides, A, so as to lock said sash -in position when closed,completes the device,

which is used as follows, viz: For the delivery of letters,

newspapers, 85e., of ordinary size, the

sash D is closed and the opening d left open butfor packages too largeto be passed through said opening said sash IOO is turned to theposition shown in Fig. 3, and such packages vpassed outward at one side.In very cold Weather, or when the office is closed, the plate H isplaced Within said opening. When the sash D is closed and looked, it issafe from removal Without breakage by persons from Without, so that,while affording ample means for the delivery of any package admitted tothe mails, my Window furnishes ample security for letters and otherarticles Within the office near said window.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1. A delivery-Window closed by a verticallypivoted sashwhich has a horizontal table, and immediately above the same is providedwith a narrow horizontal opening, substantially as and for the purposeshown.

2. In combination with the window-opening, zo the sash D, having theopening d, recess d', rabbet cl2, the table G, the pivotal bearings Eand F, the plate H, the button I, and the spring-catch K, said partsbeing arranged to operate substantially as and for the purpose 2 5 setforth.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of February, 1880. Y

GEORGE J. KREBS.
